Hello ,
I have the same issue with HP 8200 SFF ( 15 computers)
The only way I found to stop eternal restart on the bios is to boot on a USB key with acronis on It .
After acronis finish starting, (I do nothing else, just start on the USB Key) , I close acronis, it make the computer restarting , and the computer can restart on windows.
I will try your solution ...
Thanks
